Everything you need to know about suits, including what to look for when buying them, how to get them tailored, and the coats, shirts, ties, shoes, and watches to wear with them.

Rule #1
We've said it before and we'll say it again: Fit is everything. Even the world's most expensive suit will look bad if it isn't tailored to the contours of your body.

Left: Blazer ($1,595), pants ($295), and shirt ($295) by Burberry Prorsum. Tie ($130) by Band of Outsiders. Pocket square ($65 for three) by Brooks Brothers.

Rule #2
Some think button-down collars are for casual wear only, but they can work great with dressier looks as well.

Rule #3
Polka dots are a great way to bring energy to a suit. Make sure they're big enough to be recognizable, but not so large that they're goofy.

Rule #4
A tried-and-true pattern like herringbone or glen plaid in a muted shade makes an impression without crossing into the realm of garishness.

Right: Suit ($3,595) by Isaia. Shirt ($550) by Kiton. Tie ($150) by Alfred Dunhill. Belt ($295) by Ermenegildo Zegna. Shoes ($660) by Church's.

Rule #5
Visible stitches around the edges of your lapels (called pick-stitching) aren't necessarily a sign of a well-made garment anymore. However, they can be an attractive decorative flourish—as long as they're subtle. No contrast stitching!

Rule #6
Some say you shouldn't cut the stitching in your jacket pockets, because putting objects in them will cause your jacket to lose its shape. Don't listen. It's pointless to have nonfunctional pockets, and a concert ticket or a business-card holder certainly won't do any damage.

Rule #7
Some think three-pieces are stodgy, but when the waistcoat is cut close to the body and hemmed to the belt line, you'll look slim and modern.

Rule #8
Your tie bar should never be wider than your tie.

Rule #9
The difference between classic and cliché is often in the material. The timeless appeal of this gray suit begins with its super-luxe cashmere wool.

Left: Suit ($9,900) by Brioni. Shirt ($145) by BOSS Black. Tie ($225) by Isaia. Tie bar ($70) by Paul Stuart. Pocket square ($75) by Polo Ralph Lauren. Shoes ($1,015) by Hermès.

Rule #10
Always unfasten your jacket buttons when you sit. No exceptions.

Rule #11
Never fasten the bottom button of a double-breasted jacket (unless it has only a single row of buttons).

Rule #12
Avoid over-accessorizing. If you're already wearing a pocket square and a tie bar, you'll want to reconsider that clever lapel pin.

Rule #13
When wearing corduroy, steer clear of fusty wide wales, but don't go so narrow that the material starts to look like velvet.

Rule #14
A dark, patterned pocket square provides a welcome visual anchor to a light-colored suit.

Rule #15
When it comes in a sandy tan rather than the usual rust or chocolate brown, this cold-weather suit gets a dose of sunny energy.

Right: Suit ($3,895) by Belvest. Shirt ($185) by Gitman Vintage. Tie ($195) by Michael Bastian. Pocket square ($25) by Club Monaco. Shoes ($660) by Church's.

Rule #16
Save the bulky shock-resistant sports watch for the gym or your outdoor-adventure excursions. It has no place with a suit.

Rule #17
Save yourself some embarrassment: Always remove the stitching on the vents and the label on the left sleeve before wearing a new suit.

Rule #18
It's fine to flip up the collar of a casual cotton jacket, but when you're dressed more formally (say, in a black suit), you should always leave the collar down.

Rule #19
When you go without a tie, it's best to keep your shirt collar on the smaller side.

Rule #20
Call attention to special suit material—like this marled wool—by keeping your accessories to a minimum.

Rule #21
Tailoring your pants a little bit short will add distinctiveness to your simple look.

Left: Suit ($1,195) by Calvin Klein Collection. Shirt ($250) by Patrik Ervell. Shoes ($1,600) by Salvatore Ferragamo.


Patrick Grant, the owner of the Savile Row fixtures Norton & Sons and E. Tautz, shares his tailoring tips.

Rule #22
Get a Uniform

"Men do well when they find something that works for them and stick to it, rather than continually try to reinvent the wheel—one of our customers must have 20 double-breasted jackets in the same cut. If you establish your own sense of style, you don't subject yourself to the vagaries of fashion."

Rule #23
You Can't Beat English Tailoring

"I definitely have friends who wear Italian-style suits, which are softer and have less structure. But I prefer English tailoring, which gives suits more shape and a well-defined shoulder. To me, it just looks sharper."

Rule #24
Mind Your Silhouette

"You can tell a good handmade suit by looking at it from 50 yards off—it's about overall harmony and balance. The trousers should be slim, the shoulders narrow, the waist nipped."

Rule #25
Don't Go Too Short

"A suit jacket should come down to the first knuckle on your thumb. Too many people are cutting short jackets now, and they just make men look too heavy in the middle."

Rule #26
Keep Your Cuff Buttons Buttoned

"I think undoing the button on your cuff looks kind of naff. It doesn't signify quality anymore because there are plenty of working buttonholes done by machines."

Rule #27
Go For Side Vents

"Most of the suits being made on Savile Row have two vents because it's considered almost cheap work to do fewer. A jacket with one vent or no vents uses much less cloth, and it's much less sewing."

Rule #28
Gray-Flannel Suits Always Look Good

"They just work brilliantly with everything. They're elegant without being stuffy and look beautifully luxurious."


Rule #29
When your jacket is buttoned, you should be able to fit a fist between your chest and the fabric—no more, no less.

Rule #30
Before buying a suit online, try it on in a store first to make sure the shoulders fit, as sizing varies widely among brands.

Rule #31
Your jacket sleeves should reveal about half an inch of shirt cuff. If they don't, try a short size instead—you could save yourself a trip to the tailor later on.

Rule #32
Choose fabric according to how often you'll wear the suit. The most versatile option is a soft but durable wool like super 120 (a measure of yarn fineness; any higher is too delicate for daily use).

Rule #33
Your pants should sit at your waist (not your hips). You should be able to fit one finger into the waistband comfortably.

Remember, people see your coat before they see your suit. If you've gone to the trouble of putting together the perfect ensemble, you owe it to yourself to finish the look with the right top layer. Whether you want single- or double-breasted, a classic or a bold color, a solid shade or a pattern, there's a well-cut coat to suit you.

Rule #34

A double-breasted overcoat should be slim so it doesn't billow when open.

Right: Coat ($4,500) by Hermès. Suit ($3,500) by Dior Homme. Shirt ($195) by Calvin Klein. Tie ($135) by Ralph Lauren Black Label.

Rule #37
Like a gray suit, a gray overcoat is always in fashion.

Rule #38
Navy coat

    • Angry grizzly bear charges couple twice; what they did possibly saved their lives

      John and Lisa Vandenbos were scouting for fishing spots along the Lamar River in Yellowstone National Park on Saturday when they spotted an adult grizzly bear feeding on a partially consumed carcass. The grizzly bear was obviously surprised and was in no mood to share in its bounty, so it immediately charged the couple, coming to within 9 feet, according to Yellowstone National Park spokeswoman Morgan Warthin. Fortunately, the couple from Bozeman, Montana, were prepared and both quickly discharged their bear spray. “The bear initially left,” Warthin wrote. “When attempting to charge the couple again, it ran into the original cloud of bear spray.

    • Woman writes bad Yelp review because of a bodega cat, and the internet destroys her

      Don't mess with the bodega cats. Walk into any corner store a.k.a bodega in New York City, and you'll find a variety of household goods, beer, probably a deli and almost definitely a resident cat. The cats keep the rats and mice away and in return, they get to hang out inside and take naps on the chip shelf. @georgeferrer A photo posted by Bodega Cats (@bodegacatsofinstagram) on Oct 11, 2016 at 4:54am PDT Usually New Yorkers tend to ignore that bodega cats may be a health code violation, because most people would prefer to see cats hanging around than rats. But recently, one Yelper decided to break the golden bodega cat rule, and gave S.K. Deli Market in the East Village a 1 star review after noticing her bodega had a cat chilling on a stack of Budweisers. Big mistake. Reviewer Diana D, who has since deleted her post, claimed she had ordered from the bodega before, but decided to pick up her food instead of getting it delivered. That's when she noticed the adorable cat protecting its store. You gotta be a miserable gentrifying ass bitch to yelp about the bodega cat — سنكامي (@SynKami) October 24, 2016 "Besides being allergic, I wonder what the health code say(s) about this?" Diana asked in her review.  Twitter user SynKami took a screen grab of the review and shared it to his followers, harshly calling out Diana  for complaining about the bodega cat. Twitter promptly erupted, and the tweet has racked up more than 7,800 retweets at the time of writing. @SynKami @asherahresearch does she realize the cat is there to keep the rats away. Dumbazz — jaja (@JaJasTweets) October 24, 2016 @SynKami tbh, I don't trust a bodega that doesn't have a cat — Carlos LaBestia (@Arturo_Ulises) October 25, 2016 S.K. Deli Market's Yelp page was flooded with positive reviews on Wednesday, supporting both the deli and cat, who's name is Ciao Bella, according to one Yelper.   According to a piece published in the New York Times about the controversy over bodega cats, fines could cost the bodega $300 to $2,000. However, a fine for rodent feces found in a store can also land a bodega with a $300 fine. "It’s hard for bodega owners because they’re not supposed to have a cat, but they’re also not supposed to have rats,” José Fernández, the president of the Bodega Association of the United States, told the New York Times.

I am certain many of the Hall’s members and voters mean well, and I have heard nice things about their museum (which I have not visited). But the Hall, as it exists now, is so deeply flawed that it risks not only having a lack of credibility, but also a lack of validity.

      DEAR ABBY: I’m 18 and a freshman in college. My 16-year-old brother is supposed to be a junior in high school, but he’s still taking freshman classes. He has gone to school maybe twice this year. He just gave up and dropped out. All he does is stay home, sleep and text all day. It makes me angry because I don’t work right now, but I clean, cook, do laundry and take care of my younger siblings while he does absolutely nothing. Mom has given up on him. She begs him to go to school and get an education, but he yells at her and tells her he doesn’t care and he’ll just become a hobo. I don’t know what to say to him to get it through his head that he needs to finish high school. What would you do?

After the Access Hollywood recording featuring Trump making vulgar comments about women came out earlier this month, the Utah Republican said he could "no longer in good conscience endorse this person for president. It is some of the most abhorrent and offensive comments that you can possibly imagine." Later, he went on MSNBC and told Lawrence O'Donnell, "How in the world could I look my 15-year-old daughter in the eye and say, honey you know what your dad endorses Donald Trump for president, and I can't do the end of the day I've got to look at myself in the mirror and say, I call balls and strikes as I see them, and you know what, no matter which party, if you're going to act like that and that's how you think, you're not gonna get my endorsement, you're not gonna get my support.
